. cially to such a machine adapted for Weaving a tape out of wires for the purpose. of remforcing the bead of a tire.

Among the features of my invention-is the provision of'an automatic weaving machine that is rapid and efficient in operation- Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawings, Fig. 1 is a top plan view,

v Fig.2 is a view taken as indicated by the line 2 of Fi 1 Fi 3 is a view taken as indicated by the line 3 of Fig. 2, Fig. 4 is'a view taken as indicated by the line 4 of Fig. 1, Fig. 5 is a View taken as indicated by the line 5 of Fig. 2, Fig. 6 is a view taken as indicated by the line 6 of Fig. 2, Fig. 7 is a View taken as indicated by the line 7 of Fig. 6, Fig. 8 is a viewtakenas indicated by the line 8 of Fig. 6, Fig. 9 is atop plan view of the shuttle, Fig. 10 is an enlarged view taken as indicated by the line 10 of Fig. 9, Fig. 11 is aview taken as indicated by the line 11 of Fig. 9.-

For the purpose of illustrating my improved weaving machine I have shown the same as making a tape out of three wires or warp members and a single cross wire or woof member. It is obvious,.however, that the invention may be equally well applied to machines for weaving tapes with moreor fewer of such members.

From the feed rolls' the warp lwires pass through the eyes 18 of the heddle wires 19 which are arranged in two sets in the usual manner for alternate-raising andlowering to form sheds for the passage of the shuttle 20.

Each set of heddle wiresl9 is supported between horizontal bars 21 and 22 to form a unitary frame or structure .adapted to be raised and lowered. The raising and lowering of .each set of heddles is eflected by, pro-' viding the lower bar-22 with adownwardly projecting rod 23 pivotally attached at 24 to the end of a rocker arm 25 pivoted at 26.

raise and lower one of theheddle frames. 'The' horizontal bars 21 and 22 of each set are joined by vertical members 29 operating in slides 30 in thev vertical frame members 31 to permit the vertical movement of the heddles. It is to be understood that the other set of heddles is similarly raised and lowered by another rocker arm 32 provided with a similar cam roller operated by a similar cam groove in the cam wheel 33. The two cam wheels 27 and 33 .(see Fig. 8) are adjusted substantially 180 degrees with respect to each other so that the two sets of heddles will be caused to uniformly rise and fall.

The shaft 28 is adapted to be rotated by a gear 34 driven by a ear 35 which in turn is driven by the belt wheel 36 operated by the usual belt 37. 38 indicates an idler wheel to receive the belt when the machine is stopped. It is to be noted that the rocker arms 25 and 32 are pivotally mounted on the shaft 26 .but not operated thereby. The shaft 26 serves merely as a pivot for these twoarms. 20 indicates an. oscillatory shuttle adapted to reciprocate on thecurved guides 39. The outer edge of the shuttle is provided with a hook 40 adapted to slide under the overhang- It is to be understood that the guides 39 are interrupted in the center as indicated by 39 to leave a space therebetween for the vertical movements of the warp members caused by the operation of the heddles. The inner end of the shuttle is likewise supported on two curved guides 42, 42 which are mounted on the supporting plate 43 by means of thebolts 44. The guides 42 are recessed on their inner faces as indicated by 45 to accommodate the driving arm 46 for the shuttle (see Fig. 16.)

The shuttle driving arm 46 is keyed to the upper end of a, vertically mounted rotatable shaft 47 carrying the gear segment 48 at its lower end. The gear segment 48 meshes with a rack bar 49, driven by a connecting rod 50 attached to an eccentric strap 51 mounted on the eccentric 52 driven by the shaft 28.

Reciprocations of the rack bar 49 cause the shaft 47 to oscillate and thus swing the outer endof the shuttle driving arm 46. A progressively' separable. and reconnectible driv ing means exists between the shuttle and the driving arm 46 to permit them to passon opposite sides of the warp wires 11 during their arm 56 carries a cam roller 56 moving in the cam groove 57 of the cam plate 57 (see Fig. It will be seen that the cam groove 57* consistsof two curved parts drawn on different radii both having their centers at the axis of the shaft 47. It will be seen therefore that as the arm 46 oscillates the rack bar will be alternately extended and retracted to rock the shaft- 53. The ends of the shafts. 53 are provided with driving lugs 58 which are set substantially at right angles to each other. The'underside of the shuttle 20 is provided with two pairs of lugs 59, 59, adapted to be engaged by the driving lugs 58, as shown in Fig. 15. The lugs are so arranged that as the shaft 53 rocks first one of the lugs 58 and then the other will become disengaged from the lugs 59 on the bottom of the shuttle. Theirangularly and size is such that preferably there is no interval of time when both are entirely disengaged. That is, as one becomes disengaged, the other is already partly engaged. The cam groove 57 is so formed that as each pair of lugs 59, 59 passes the center where the warp wires are lying, the corresponding driving lug 58 will be disengaged therefrom to permit relative movement of the warp wires between the pair of lugs 59, 59'and the lug 58. During this movement of the shuttle. the same is driven by the other lug 58. Likewise, in the return movement the. driving connection is progressively separated and reconnected in order to permit the driving arm -l6 to pass below the warp wires and the. shuttle to pass above. In Fig. 17 one of the lugs 5S is shown infull drivingconnection between the lugs 59. 59 on the shuttle 2t).

It is to be understood thatthe shuttle 20 carries the usual bobbin 60containing the woof wire 61 which is fed out through any suitable tension means. I have here shown the wire 61 as passing over the two rollers 62 and 63 and thence through the feeding eye 64.

Suitable tension on the bobbin 60 may be provided in any desired manner. I have here shown a friction shoe 65 pressed against the bobbin 60 by the spring 66. I have here shown the roller 62 as carried on the end of an arm '67 which is pivoted at 68 and carries the friction shoe 65 at its other end. In this form of device. tension of the woof member 61 against the roller 62 operates to release to a certain extent the friction of the shoe 65 on I the bobbin 60.

\Vhile I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention disclosed in the appended claims, in which it is my intention to claim all novelty in my invention as broadly as possible in view of the prior art.
